Barcelona midfielder Arturo Vidal is sent off. He fouls Mario Rui and goes head to head with him. In that weak headbutt way footballers do. The referee shows him his two yellow cards in a row and off you pop Arturo.

Leon Goretzka on for Thiago for Bayern Munich. They do have a class squad to be fair.

Not long left as Barcelona bring on Ansu Fati for goalscorer Antoine Griezmann.

Look at the Bayern players running back, their desire is fantastic. They have given Chelsea a lesson tonight.

"Football's Coming Home" is the song from the stands. You've got to assume it's Bayern fans singing it.

I've got to say that was some good VAR work. Didn't take much time at all.

No idea why Chelsea fans applauded Marcos Alonso on his way off.

It's not a punch, it is an open arm. I think we can understand that because he went to the monitor.

I don't know why Marcus Alonso is being applauded off. He's done his team no favours at all.

Jorginho and Marcos Alonso will both miss the second leg in three weeks as Chelsea try to overturn this deficit. Good luck with that...

Chelsea defender Marcos Alonso is sent off. He caught Robert Lewandowski in the face with a stray arm. He meant that.

Crazy stuff from Marcos Alonso to knock over Robert Lewandowski 25 or 30 yards out. Yellow card and a shooting chance from this free-kick.

That was Robert Lewandowski's first Champions League knockout goal in over two years. He scored twice against Besiktas at this stage in 2018.

Tammy Abraham was on his heels on the six-yard line. He's going to be proactive, you can't be reactive in that situation. He's just got to gamble in that situation.

Chelsea haven't had a million chances tonight - but there have been two or three where a centre forward should be tapping home. Tammy Abraham is nowhere to be seen from Pedro's low cross.

The record for Champions League goals scored in London by players not representing an English club is six - shared by Lionel Messi and Serge Gnabry.

You wonder what is going through Frank Lampard's mind? They have been out-classed tonight.
